    Grooved concentric reducers are cone-shaped pipe fittings with grooved connections that reduce the size of a pipeline in a symmetrical and concentric manner, while keeping the centerlines of the two pipes aligned.

    Features
    • Made of materials such as ductile iron, stainless steel, or carbon steel, providing high wear resistance and corrosion resistance.
    • Available in various sizes and pressure ratings to accommodate different applications.
    • Enables to join the two pipes of different diameters.
    Recommended Applications

    Grooved concentric reducer is commonly used in industrial and commercial piping systems, such as gas pipelines, water supply pipelines, etc., where a reduction of the pipe size is required to accommodate changes in flow or pressure.
